The lack of probability-fatigue data is still a problem limiting the fatigue optimization of additively manufactured metallic materials.Modelling the probability density of fatigue life random variable is essential to predict the durability of structures.In the paper an experimental data for additively manufactured 18Ni300 maraging steel are studied fitting them to a proposed B-spline model.Parameters of the B-spline basis functions were obtained through a nonparametric density estimation technique.Obtained probability density functions were compared with maximum likelihood estimated Weibull density functions.
